/**
 *使用RabbitMQ
 * 1、引入amqp场景; RabbitAutoConfiguration 就会自动生效
 *
 * 2、给容器中自动配置了
 *       RabbitTemplate、AmqpAdmin、 CachingConnectionFactory、 Rabbi tMe ssagingTemplatej
 *       所有的属性都是spring. rabbitmq
 *        @ConfigurationProperties(prefix = "spring.rabbi tmq")
 *       public class RabbitProperties
 * 3、给配置文件中配置spring. rabbitmq 信息
 * 4、@EnableRabbit: @EnableXxx; 开启功能
 * 5、监听消息 ：使用@RabbitListener;必须有@EnableRabbit
 * @RabbitListener:类+方法上（监听那些队列）
 * @RabbitHandler：标在方法上（重载区分不同的消息）
